Instructions

1. Caramelize the sugar

   Pour 100 g of white sugar into the bottom of a pan, heat over medium heat without stirring. Let the sugar melt and turn an amber color.

   Time: PT5M

2. Caramelize the apples

   Add the apple pieces, lemon juice and a pinch of salt to the pan. Stir regularly for 10 minutes until the apples are golden and well coated with caramel.

   Time: PT10M

3. Cool the caramelized apples

   Transfer the apples to a dish and let them cool completely before handling.

   Time: PT5M

4. Prepare the crumble

   In a bowl, rub the softened butter with the almond powder, brown sugar and flour using your fingertips until you obtain a sandy texture with irregular pieces.

   Time: PT5M

5. Bake the crumble

   Spread the crumble on a baking sheet lined with parchment paper and bake for 12 minutes at 180°C until golden and crisp.

   Time: PT12M

   Temperature: 180°C

6. Prepare the choux pastry (base of the Japanese biscuit)

   In a saucepan, bring the milk and 30 g butter to a boil. Remove from heat, add the flour all at once and stir vigorously until you obtain a homogeneous dough.

   Time: PT5M

7. Incorporate the eggs

   Transfer the dough to the stand‑mixer's bowl. Gradually add the 6 whole eggs then the 2 reserved egg whites, continuing to beat on medium speed.

   Time: PT5M

8. Make the meringue

   In another bowl, beat the 4 egg whites to stiff peaks with 80 g sugar, lemon zest, orange zest and vanilla extract.

   Time: PT5M

9. Fold the meringue into the choux pastry

   Gently fold the meringue into the choux pastry by lifting the mixture with a spatula, so as not to break the air bubbles.

   Time: PT3M

10. Bake the Japanese biscuit

    Spread the dough on a parchment‑lined sheet (about 5 mm thick). Bake for 12 minutes at 180°C until the biscuit is lightly golden but still pliable.

    Time: PT12M

    Temperature: 180°C

11. Cool the biscuit

    Remove the biscuit from the oven and place it on a rack to cool completely before handling.

    Time: PT15M

12. Prepare the whipped cream

    Whisk the very cold heavy cream with powdered sugar and vanilla extract until a firm, airy consistency is achieved.

    Time: PT5M

13. Prepare the flavoring syrup

    Mix 2 tablespoons water, 2 tablespoons sugar and, if desired, 1 tablespoon Calvados. Heat lightly until the sugar dissolves.

    Time: PT3M

14. Moisten the biscuit

    Using a brush, coat the cooled biscuit with the flavoring syrup over the entire surface.

    Time: PT2M

15. Assemble the Yule log

    Spread a generous layer of whipped cream over the biscuit, arrange the caramelized apple pieces, then sprinkle with crumble. Gently roll the log starting from one side.

    Time: PT5M

16. Chill

    Wrap the log in cling film and place in the refrigerator for 30 minutes to set the shape.

    Time: PT30M

17. Finishing and serving

    Trim the ends for a neat appearance, decorate the top with a few apple pieces, extra crumble and dust with powdered sugar for a snow‑like effect.

    Time: PT5M

Chef Tips from the Video

• Use slightly tart apples (Granny Smith) to contrast with the sweet caramel.
• A splash of Calvados in the syrup adds a typically Norman note that elevates the apples.
• For an even more elegant presentation, dust the top of the log with edible gold powder.

Troubleshooting

Storage

Refrigerator: Keep the log wrapped in cling film for up to 2 days in the refrigerator.

Freezer: Can be frozen for 1 month, but the crumble will lose its crunch.

Room temperature: Consume within 2 hours of decorating, otherwise keep refrigerated.

Make-Ahead Tips

• Prepare the crumble and the biscuit the day before; store them separately in airtight containers.
• Caramelized apples can be made 24 hours ahead and kept in the refrigerator.
• Whipped cream can be kept chilled; whisk it just before assembly.
